Your roof is your home's first line of defense against the elements, and here in the Pacific Northwest and Washington State, it faces more challenges than almost anywhere else. Constant moisture creates the perfect environment for moss, algae, and debris buildup — which can shorten the life of your roof if left untreated. At Foundation Cleaning, we specialize in safe, effective roof cleaning and moss treatment services. Our goal is to protect your investment, extend the lifespan of your roof, and keep your property looking its best year-round.
